Application filed March 26, 1926. Serial No. 97,791.

of the dolly, and blade members disposed ad-,

jacent said waterways to forcibly project a portion of the water throughsaid ways, dur

mg reciprocation of the dolly.

A further object lies in the provision of a dolly member fashioned in amanner to greatly increase the water agitation during its reciprocation.p

A still further object is in the provision of a dolly member of simpleconstruction, fashioned in a manner to cause considerable wateragitation above the disk member, as well as therebelow.

Other objects will appear in'the following specification, taken inconnection with the annexed drawings, in -which- Fig. 1 is a perspectiveview of a power washing machine with the tub member there of cut awayfor a clearer disclosure of the dolly member. 1 Fig. 2 is across-sectional view of the dolly. Fig. 3 is a plan view, from below, ofthe dolly, and

Fig. 4 is an end elevation of the water circulating-element shown inFig. 3.

Referring to the drawings, in Fig. '1 there is shown a perspective of myparticular dolly located in its normal operative'position upon a wellknown type of dolly washing machine. Referring generally to thepower-operated washing machine which is of conventional type, we find aframe member 10, upon which as is fixedly located the tub member 11.Power means for driving the dolly includes the well known electric motor12, pulley wheel 13, belt 1a, and the driving gear wheel 15. Reductiongears between the pulley wheel 13 and the driving gear 15 are shown at16. Pivoted to the driving gear 15, at 17, is av lever 18, which ispivotally attached at 19 to a substantially vertically disposedoperating memer 20, pivoted at 21 to a supporting bracket 22,

' fixedly attached to the main frame 10. A

rack 23 is pivotally attached to the member 21 at 24, said rack engaginga gear 25 upon which is slidably supported the vertically disposed driveshaft 26, to which is attached the dolly member generally designated as27, the

latter forming the basis for the present application.

The dollyincludes the plate or disk 28,

having the upwardly projecting hub portion 29, into which is adapted tobe inserted the driving member 26 above described, suitable means beingprovided for attaching said driving member to the hub 29. Disk 28 hasblades 30. The disk 28 also has fashioned thereon a series of waterwaysgenerall referred to as 31. These waterways inclu e al- .projecting fromits lower face a pluralityv of ternate series of waterways opening in anangular manner through the upper and lower faces of the disk. One of theseries of waterways is fashioned by slightly elevating the disk, as at32, to form angular passages 33, through the face of the disk. The otherseries of waterwaysincludes depressing the disk as at 34, to form thebefore-mentloned alternate waterways, which open through the upper faceof the disk, as at 35, rather than through the'lower face of the disk,as is the case with the before mentioned slight elevation of the disk,as shown at 32.

The operation of the washing machine is thought obvious in View of thefact that the construction is entirely conventional and thereciprocation of the rack produces similar reciprocation of the dolly.The reciprocation of the dolly member in one directlon results inprojection by the blade members of a portion of the water through theopenings 33 in a forcible manner. The op osite direction of movement ofthe dolly resu ts in a forcible projection of water through the openings35 of the alternate set of waterways, the same being fashioned bydepression of the disk, as shown at 34.

It may be seen from the above that not only is there the normalagitationofthe water below the disk, such as accompanies many wellknown'types of dolly,'but also there is considerable agitation of thewater above the dolly, due to the forcible projection ofa portion of thewater through the .an ularly disposed waterways opening throug the upperand lower faces of the disk. o

What I claim is: I 1. The combination with a washing machine, of a dollycomprising a. disk member having fashioned thereon a plurality ofangularly disposed waterways opening through the upper and lower facesof the disk,- said waterways being inclined toprovide inclined waterchannels, blade members disposed on the lower face of the disk adj acentsaid water- :ivalys, and mechanism for reciprocating said 2. Thecombination with a washing machine, of a dolly and means forreciprocating,"

same, said dolly comprising a disk having blade members disposed on thelower face thereof, waterways fashioned in the disk adjacent the blademembers, and inclined channelways formed upon the waterways at an angleto said disk to permit forcible pr'ojeofashioned with a plurality ofopenings through the upper and lower faces thereof,

said disk including alternate elevations and depressions of thoseportions of the disk lying ad acent said openings, to form the openings.therethrough, said elevations and depressions being disposed at an angleto the disk to provide inclined water channels. In testimony whereof, Ihave hereunto afiixed mysignature.

JOHN RQCKE.
